Self Draining Mop System

ABSTRACT

The mop has a hollow pole ( 1 ) the center of which has a piston ( 3 ) which is activated from the outside with a movable grip ( 6 ), so that said piston ( 3 ) may reduce the elevation of a pressure chamber ( 4 ) established in the lower area of the pole ( 1 ), which communicates directly with a push cylinder ( 10 ) with a larger diameter, which reinforces said pole at the bottom and in the center of which works a push plunger ( 13 ) which supports the head ( 24 ) the mop cloth ( 25 ), also actuating said push plunger ( 13 ) on a pair of side cams ( 16 ) which when resting adjust on the exterior to the push cylinder ( 12 ) but that in the initial downward movement phase of the plunger ( 13 ) they tilt outward locking into a perimeter tab ( 18 ) of the wringer opening ( 19 ) also part of the opening of the bucket that holds the water, so that the tendency of the pole ( 1 ) reversing during the wringing phase is eliminated by locking said pole ( 1 ) to the wringer ( 19 ) using the mentioned tab ( 18 ) of the latter. The manual effort needed to wring the mop cloth ( 25 ) is therefore drastically reduced.

OBJECT OF INVENTION

This invention refers to a mop, which means a cleaning tool, such as those used to wash floors and which consist of mop cloth or an actual cleaning tool, part of a pole with an appropriate length so that the user may work while standing, a tool that is complemented with a bucket provided which has a mesh wringer at its opening and generally barrel-shaped, on which the water from the mop cloth is eliminated with pressure and turning same against the wringer, moved using the pole of the mop.

The object of the invention is to obtain a mop that allows to wring its mop cloth with minimal effort by the user of the product.

The invention is therefore in the area of cleaning tools, particularly at the household level.

BACKGROUND OF INVENTION

As is already known, when normally using a mop, the operation of wringing the mop is frequently repeated, inserting the mop into the wringer and simultaneously performing a rotating movement at the same time, which brings noticeable effort both at the level of the wrist and the arm as well as the backbone by the person who is doing the cleaning.

In an attempt to alleviate this pushing and twisting effort, elastic wringers are known to be used, which as the user pushes the mop into the wringer it tends to close, attempting to squeeze the mop cloth of the mop as much as possible.

There are also devices known to have handles where a pressure handle deforms the mop cloth and wrings same, but like in the above example and even when there is a positive effect, the effort by the person using the mop is still considerable.

The lever systems also present the additional problem that the user loses his/her natural position and ease, having to bend to activate said lever.

SUMMARY

The mop proposed by the invention makes up a noticeable technological advance in this field, upon obtaining that the wringing of the mop cloth can be made with minimal effort.

For that purpose and more specifically said mop, since it is conventional and key feature it incorporates a pole with a mop cloth, with an appropriate length to allow the user to work while standing, it focuses its characteristics in the fact that at the center of the mentioned hollow pole, it includes a rod with a mobile grip at the end, which can be moved axially over the pole, said rod is reinforced at the bottom by a piston, which establishes an air lock for a pressure chamber set in the center of the pole and under said piston, the bottom of the mentioned chamber extends in the lower extremity of the pole, to configure a push cylinder on which there is a plunger to where only the mop cloth is attached, and is movable so that it may later be replaced when needed.

Said push plunger, in addition to acting as a means for the mop cloth to move also actuates on a pair of cams, placed in diameter and mounted tilted on the wall of the cylinder itself so that said cams that laterally adapt to the push cylinder when resting, tilt outward at the start of handling the movement of the plunger, locking itself on a tab that slightly squeezes the opening of the wringer, with which the pole assembly remains immobilized during the tendency of the upward movement of same which occurs with the pressure of the mop cloth against the wringer, so that all of the energy applied by the user is harnessed for the wringing itself, with minimal effort given the difference in diameters between the pressure chamber installed in the center of the pole and the diameter of the push cylinder, an effort which supposes a long trajectory of the movable grip, for a short but sufficient trajectory of the push plunger.

According to characteristics of the invention, another provision is that at the bottom end of the push plunger it has a blind and axial hole, with a flare at the bottom, intended to receive and attach the head of the mop cloth, which occurs in a cap equipped with two axial spindles, one at the top, affected by a diameter cut and with a perimeter shoulder to interlock at the bottom of the axial hole and blind of the pushing plunger, while the bottom part also has an expansion on its free end to attach the mop, strands or cloth that make up the actual mop, with the help of a washer, with the special feature that the mentioned cap includes a pair of pins pointing upward on its lower part, in front of the respective cams, so that when there is an ascending traction on the moving grip of the mop, or when it tends to move upward due to a recovery or return spring, the mentioned pins act first over the cams by unlocking them from the internal perimeter tab of the wringer's opening.

DESCRIPTION OF DRAWINGS

To complement this description and with the object of helping to better understand the characteristics of the invention, according to a preemptive example of the practical execution of same, we attach as an integral part of said description, a set of drawings which illustrate but are not limited to representing the following:

FIG. 1.—Shows, according to a schematic representation a side view, a mop made according to the object of this invention.

FIG. 2.—Shows, according to a side elevation and diameter view, the mop from the above figure without the mop cloth.

FIG. 3.—Shows a similar view as FIG. 2, but it also shows the mop cloth and its wringer.

FIG. 4.—Finally shows a detailed view of the diameter section of the head of the mop cloth.

PREFERABLE EXECUTION OF THE INVENTION

By viewing the mentioned figures it is evident how the recommended mop consists of a hollow pole (1), that closes at the top end with a handle or handgrip (2), conveniently attached to same, inside the space of said pole (1) there is a piston (3), under which there is a pressure chamber (4), which will be described below, and said piston (3) is supported by a rod (5) that is directed towards the top end of the pole and can be moved with a movable grip (6), mounted on the outside and sliding over the pole (1), as can be perfectly seen in FIG. 2, the rod (5) works together with the movable grip (6) with a pin (7) which actuates in the center of a groove (8) on the pole (1) itself, the length of which determines the range of axial movement provided for the piston (3).

This pin (7) also acts as a means of attaching a return spring (9) to the bottom end, set between said pin and the top end (10) of the pole, for example with the combination of another pin.

The pole (1) is reinforced at the bottom end by a push cylinder (11), with a considerably wider diameter, for a chamber (12) also with a larger diameter than the chamber (4), the chamber (12) in which a push plunger (13) is used and which is assisted by at least one tight joint (14) that ensures the tightness of all chambers (4) and (12).

On the side wall of the push cylinder, below the operating area of the tight joint (14), there are two windows (15) in which each cam (16) actuate tightly, diametrally opposed, mounted tilted on the respective axles (17) inserted in said windows (15), with the mentioned push plunger (13) having a front side operation on said cams (16) at the start of its trajectory.

These cams (16), in the said initial phase of the movement of the push plunger (13), tilt outward so as to interlock into a ring or tab in the inside perimeter (18) provided at the opening of the wringer (19), so that after this start in the ascending movement into the push plunger (13) the cams (16) lock the pole (1) completely in the mentioned perimeter tab (18) of the wringer, which eliminates the tendency to move the pole upward due to the wringing pressure and said pole (1) is rigidly joined to the wringer (19).

According to the variance in performing FIG. 3, it is feasible to house in the pressure chamber (4) a second piston (20) that is part of the push plunger (13) with a spring (21) which works when compressed.

In any case, the push plunger (13) has included at its lower end a blind and an axial hole (22), with a perimeter flare at the bottom (23), to receive and attach the head (24) of the actual mop or mop cloth (25). In this sense each head (24) has two axial rods, one top rod (26), with a diameter cut (27) on its free extremity and a perimeter nerve (28) to interlock during the expansion (23) of the blind and axial hole (22) of the push plunger (13), so that the mentioned diametral cut (27) allows for elastic deformation, specifically the radial contraction, of said rod (26) so that it may cross the lower and narrower area of the blind hole (22). The lower rod (29), also reinforced by its free extremity in a perimeter nerve (30), is made to attach the mop, which remains partially snapped in a type of inverted bucket (31) on the head, and finally held with a washer (32).

The head (24) includes at the top and side a pair of ascending pins (33), and diametrally opposed, operationally facing the cams (16), so that when said head (24) starts the upward movement, it acts on said cams (16) causing these to unlock with respect to the perimetral tab (18) of the wringer (19), which allows the mop to be removed from said wringer.

Finally it should be indicated that the pressure chamber (4) may be occupied with air, water or any other type of gas or liquid, and that the movable grip (4) may be replaced by a push-button that acts on a mechanical and/or electric pump, as well as the attachment of the head (24) of the mop to the push plunger (13), this may also be done using an interior or exterior screwed joint, as long as in limit situations of the assembly of the pins (33) they remain facing the cams (16). 

1. SELF-DRAINING MOP SYSTEM the type that from the mop's own handle with a start plunger, we activate a traction or push body solidly connected to the end of the mop. Characterized because in the start-up body there is a drive system, through a movable grip, when slid on the outside of the cylinder, the plunger, with a catch in its pressure path, activates the traction body which consists of a plunger embedded in its traction cylinder and solidly connected to the end of the mop, one or many plunger catches and a rotary groove so that the cams coupled to its shaft may move and connect to the receiving platform as the plunger moves, preventing that the cylinder and traction body solidly connected to the end of the mop, moves back and moves while increasing the pressure against the receiving chamber where we previously inserted the mop, draining same. When the movable grip slides to its initial position and, it said case, aided with a spring or return system, the traction plunger moves back, the cams close and they disconnect from the platform, thereby releasing the drained mop.

The upper cylinder bushing has the mission of closing the cams or tabs located in the push cylinder when it returns to its initial position, catching same against the cylinder, avoiding any movement and allowing that they may open when starting the downward movement of the working plunger. A support tray serves as a stop in the working rod and at the same time receives the pressure for the draining of the mop that next to the platform or support washer anchored to the lower rod, catches the mop against the lower tapered bushing avoiding its movement or disengagement. Through the lower rod and with its tapered anchor lug and orifice or drilling anchors the platform or support washer.
